Quintus Sulpicius Camerinus Praetextatus was a consul or consular tribune of the Roman Republic in 434 BC. Sulpicius belonged to the patrician Sulpicia gens. Sulpicius is the first named member of the branch within the gens known as the Praetextati. Sulpicius was possibly the son of Servius Sulpicius Camerinus Cornutus, consul in 461 and decemvir in 451 BC. Filiations indicate either Praetextatus or Quintus Sulpicius Camerinus Cornutus, consular tribune 402 and 398 BC, as the father of , consul suffect in 393 BC and consular tribune in 391 BC. A later Praetextatus named Servius Sulpicius Praetextatus, consular tribune in 377, 376, 370 and 368 BC, is probably a descendant of Quintus Sulpicius.
